Abstract:
A chromene compound which can exhibit excellent photochromic properties. The chromene compound is represented by the following formula (1). In the formula, at least one of R1 or R2 represents the group having the radical-polymerizable group, wherein the group having a radical-polymerizable group is represented by the following formula (2) (wherein R10 represents a linear or branched alkylene group having 1 to 10 carbon atoms and l represents an integer of from 0 to 50); and the ring Z that is represented by the following formula (Z) and is spiro-bonded to a carbon atom located at position-13 in the formula (1) is preferably an aliphatic cyclic group that may have a substituent, the group having 3 to 20 carbon atoms for forming the ring together with the carbon atom at the 13-position, or the like.
